We have already seen how motivation is geared to the animal’s survival requirements, but now we need to see how it copes with various ‘ecological’ problems — finding a living area, fo

Having decided to feed, it must then decide where to feed, what sort of food items to take, when to move to a new feeding area and so on.. This applies as much to herbivores and detritus feeders as it does to animals which hunt mobile prey.

When we look at how organisms reproduce, however, we notice that most of them reproduce sexually and that many of their most conspicuous features and acti

The presence of conspecifics and animals of other species is likely to influence practically every behaviour an animal performs. The efficiency of breeding behaviour, feeding, predator avoidance, even thermal regulation may be affected by the degree of proximity of oth

In many cases these signals are the result of deliberate and complex actions which have evolved specifically to influence the behaviour of other animals.

As Harvey and Greenwood. point out, however, it is important to emphasise that predation need not be a limiting factor in a prey population for a genetically based anti-predator strategy to evolve.

As with the topics discussed in preceding chapters, therefore, we shall examine variations in social organisation from an adaptive viewpoint.
